DAMPER-REGULATOR FOR FURNACES.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed J nuary 28, 1905. Serial No. 243,1 6-

To all whom it may concern.-

Be it known that I, WILLIAM F. PIoKLE, of the city of Decatur, county ofMacon, and State of Illinois, have invented a certain ImprovedDamper-Regulator for Furnaces, of which the following is aspecification.

This invention is intended to provide means for controlling the draft offurnaces; and the object is to enable the dampers to be shifted eitherfrom the basement or from the first floor.

The invention is exemplified in the structure hereinafter described, andit is defined in the appended claims.

In the drawing forming part of this specification the invention isillustrated in perspective, the floor and a wall being shown in sectionand two damper-regulators being included in the drawing.

A plate 1 is secured to a plinth or baseboard in a vertical positionimmediately above the floor, and such plate is slotted at intervals toform the cross-bars 3. The slots are shown at 2, and they are preferablydisposed in two sets or tiers. Another plate A is secured to the fiooradjacent to plate 1, and this horizontal plate has a pair of oblongslots at 5. A regulatingbar 6 is shaped to slide in one of the slots 5,while fitting the same somewhat closely. A lift-ring? is formed on theupper end of bar 6, and a hook 8 projects from the lift-ring in positionto engage the bars 3 in one of the tiers of plate 1. The bar 6 extendsthrough the floor and below the same for several inches. Its downwardextension preferably assumes the form of a rod, as shown at 6. A ring,as 6", is preferably formed on the lower end of the rod, and a lug 9projects at right angles from the bar just below the floor. The lugextends in the same direction as the hook 8, and a chain 10 runs fromthe lug, around a pulley 11, and off to a damper of the furnace. Anotherregulating-bar 12 has a lift-ring 13, a hook 14:, a rod extension 12, aring 12 on the rod extension, and a lug which is in this instanceobscured by the floor, but is identical with lug 9 of bar 6. A chain 16runs from thelug of bar 12, around a pulley l7, and off to an otherdamper of the furnace.

The two bars and adjuncts thereof are precisely the same. Each embodiesmy invention, and both are shown for the reason that two are usuallyneed ed to completely control a furnace. The location of the pulleys andthe directions taken by the chains are suggestive merely, and thesefeatures are of course varied to adapt the use of the regulators tovarious conditions, depending upon the location of the furnace withrelation to a convenient situation for the regulators and upon suitablesupports for the pulleys.

The regulating-bars are set higher or lower to vary the positions of thedampers by manipulating lift-rings 7 and 13 when the operator is on thefirst floor and by manipulating rings 6 and 12 or the rod extensionswhen the operator is in the basement. In either case the bars are rockedin slots 5 to disengage the hooks, are raised or lowered to the desiredextent, and are again rocked slightly in the slots to reengage thehooks. The bars being noncircular in cross-section are unable to turn inthe corresponding slots and are therefore always in position to presentthe hooks to the cross-bars. The chains pull the hooks toward thecross-bars and facilitate the operation of hooking the regulating-barsin place.

The cross-barred plate 1 illustrates the preferred way of providingsupports for the regulating-bars; but it is obvious that the essentialthing is a plurality of bars or equivalent thereof at different heightsand that these may be provided in various ways.

By the use of my invention the dampers may be shifted from above in theusual way and may also be shifted from the basement through the sameshifting mechanism. If, for instance, the dampers are found to be openwhen it is desired to supply the furnace with fuel, it is not necessaryto run upstairs to unhitch a regulating-chain in order to preventsmoking up the house by opening the fueldoor while the dampers are alsoopen, and other advantages will readily occur to those skilled in thecare of furnaces.

I claim 1. In a damper-regulator, the combination of a set of cross-barsarranged one above another and above a floor, a draft-regulating baradapted to extend through the floor, a hook on the upper end of the bar,a lug on that part of the bar extending below the floor, said lugextending in the same direction as the hook, and a chain connecting withthe lug.

2. In a damper-regulator, the combination of a set of cross-barsarranged one above another near the floor of a room, anon-circularregulating-bar having a hook to engage the cross-bars, afloor-platehaving a slot conforming to the cross-sectional outline of thelating-bar extends, a lug on the regulatinga lug on the bar below thefloor and a damperbar beneath the floor and a damper-controllingcontrolling chain connecting with the lug.
